Do the units turn on when power is supplied to them or do you have to press a power button?

You have to power them on at least the way mine are wired. They are really good though I have 2 of them and my kids love them! You can watch the same thing on both screens with one disk or you can watch 2 seperate things at a time if you have 2 of them.

You have to push the button to turn on the power .. The units can connect to eachother as well. There are no external speakers , you have to use car stereo or headphones .. I am pleased with the quality .. The headrest isn't the best but it doesn't look bad

You have to press the power button on the unit or the remote that is included.

It does not. I just confirmed it with the one I just got - unplugged it - pushed the power button - nothing. Nice display though. The rechargeable battery seemed like a weak feature anyway because it was only rated at ~1-hour of use.

The power switch is on the top edge of the chassis all the way on the left. There is a small blue light that illuminates when the power is on. Not sure if you are asking because you are having any trouble with this, but I have found that I sometimes have trouble "waking up" the unit after it has been in sleep mode for a time. I hold the power button down for a long count to make sure that the unit is really powered off, and then it usually starts up right away with the boot sequence/password, etc.

These lights can only be turned on if they are unpluged. But if the power goes out and they are pluged in, then they will turn on.

Mine automatically powers on when the power is turned on to the unit. I don't have to push the power button to turn it on. I just have one camera hooked up and it automatically uses that camera. Input 1.

I have learned to have the right touch with the power on button. If you tap it or press it quickly, it gives you the date and time. To turn the unit on requires a longer, firm press, but not too long. If that doesnt help you, your unit might need repair.

As opposed to? Yes, you have to turn it on and off by pushing the power button.

No. The unit will not stay powered on. As soon as you turn it on, it turns off.

You double click the power button and the light will turn off, do the same to turn it on. The directions were in the very small and hard to read manual you received with it

I just got mine. It has a power button and a remote control. You can turn off the power from both. I suppose there is still some power draw, so you might want to consider unplugging it.

There is no "on/off" button. They must be plugged into the wall to turn on, unplugged to turn off.

You have to press the power button for at least 6 or 7 seconds. Then, if you're lucky, it will come on.

There is no power button, the activation happens by using a switched outlet. The switch needs to be wired by an electrician.

Hate to add a second answer but realized i did not really answer the question. On 16 you have to push the mode selection button to turn on power to the load

No. Once the unit is turn off, it will not turn on with out pushing the power button on the "key pad" or remote. If you unplug it for example, while it's on, when you plug it back in it needs to be physically turned on with the power button.
